You have 3 pico fuses by your fly-back transformer. One of them blew that controls your convergence circuit. Your TV now thinks that it is a Basic CRT set with 1 tube. Find the bad fuse and replace with a 1/2 amp pico fuse, and re-solder all the pins of your fly-back transformer. Your menu should have the convergence option again.
You need to resolder the flyback transformer and replace fuse FL221 off pin 11 of the flyback transformer. The convergence power supply is not coming on so system control thinks a convergence circuit is not installed.
Projection TV sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the video to look normal. When its out of alignment the video will look 3D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the TV menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired. This is a very common failure on these projection sets and a fairly simple DIY fix. All projection sets including Samsung, RCA, Sony, Philip Magnavox, Panasonic, Pioneer, Akai, GE, JVC, Toshiba, and others at some point will have the same problem.
Common Symptoms include.... •Screen looks 3D •Colors don't line up •One or more colors can't be adjusted when using the convergence menu. •Screen is bowed or warped. •TV shuts off after powering on. Power light will blink. TV may also make a chirping noise.
Here are some photos of convergence problems

It should be in the options menu. If not often RCA will drop the option when the convergence ICs go out and often the set will shut down. Heres alink that should be able to help you get a manual and parts if needed. If they dont have your manual leave an email and they should be able to get one quckly usually within an hour or two. http://servicemanuals.vstore.ca/
